  • This service provides header and observation data for gravity stations located throughout continental Australia and Remote Offshore Territories. Data sources include the Australian National Gravity Database (ANGD) and the Australian Fundamental Gravity Network (AFGN) maintained by Geoscience Australia (GA). Data has been obtained by Surveyors, Commonwealth and state/territory Governments, private companies, and educational institutions. Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

  • This service contains the NATMAP 1:250,000 scale maps, from the NATMAP Digital Maps 2008 DVD. The large scale single mosaic map covers the entire continent, and is based on the Geocentric Datum of Australia 1994 (GDA94) geographic projection. The maps have been revised using a variety of data sources, including SPOT and Landsat satellite imagery, other government agency information and data supplied by private companies and individuals. The original DVD was produced by Geoscience Australia's National Mapping Division and its predecessor, the Australian Surveying and Land Information Group (AUSLIG).

  • This service is produced specifically for the Northern Australia Project and may be removed or changes without notice. This web service shows land tenure in Western Australia and Queensland north of the Tropic of Capricorn and the whole of Northern Territory. This service uses PSMA 2015 land tenure data for Western Australia, and PSMA August 2016 for Northern Territory and Queensland.

  • Analytical results and associated sample and analysis metadata from the analysis of minerals in earth material samples.

  • This web service provides access to datasets produced by the mineral potential assement of iron oxide-copper-gold (IOCG) mineral systems in the Tennant Creek – Mt Isa region. The mineral potential assessment uses a 2D, GIS-based workflow to qualitatively map four key mineral system components: (1) Sources of metals, fluids and ligands, (2) Energy to drive fluid flow, (3) Fluid flow pathways and architecture, and (4) Deposition mechanisms, such as redox or chemical gradients. For each of these key mineral system components theoretical criteria, representing important ore-forming processes, were identified and translated into mappable proxies using a wide range of input datasets. Each of these criteria are weighted and combined using an established workflow to produce the final map of IOCG potential.

  • Australia - Offshore Minerals Act 1994 - Mineral Blocks - epoch 2014a. This service displays the Australian Mineral Blocks - Aligned with the current Australian Maritime Boundary Dataset. Refer to the metadata of the geodatabase for a detailed abstract relating to the data.

  • Petroleum Blocks cut to the AMB 2014a epoch. The service contains the Blocks as defined under Section 33 (3) of the Offshore Petroleum and Greenhouse Gas Storage Act 2006. Coverage includes indicative areas of coastal waters and land, within the constitutional limits of the States and territories.

  • This web service provides access to gridded data produced by Geoscience Australia from studies of Australian groundwater and hydrogeological systems.

  • This service delivers the base of Cenozoic surface and Cenozoic thickness grids for the west Musgrave province. The gridded data are a product of 3D palaeovalley modelling based on airborne electromagnetic conductivity, borehole and geological outcrop data, carried out as part of Geoscience Australia's Exploring for the Future programme. The West Musgrave 3D palaeovalley model report and data files are available at https://dx.doi.org/10.26186/149152.

  • The Surface Geology web map service provides two seamless national coverages of Australian bedrock and surficial geology, compiled at 1:1 million scale (displays only at scales less than 1:1500000), and 1:2.5 million scale (displays only at scales greater than 1:1500000). It also contains 1:5 million scale geological regions and metamorphic geology. The service represents outcropping or near-outcropping bedrock units, and unconsolidated or poorly consolidated regolith material covering bedrock.
